Fewer than 7,000 tigers remain in the wild, and this film follows the Wildlife Conservation Society biologists trying to keep that number from hitting zero. In the Russian Far East, American biologist John Goodrich and tracker Kola Ribin follow a radio-collared 19-month-old male as he leaves his mother's territory and wanders near the village of Tanay, one of only about 350 tigers spread across a thousand kilometers of coast, where any tiger that strays into a village risks being killed. Nearly 4,500 kilometers southwest, biologist Tony Lynam and a WCS colleague go undercover in Bangkok's weekend market, rigging a bag with a hidden camera to document the illegal wildlife trade that has pushed sales underground but left Thailand a hub for trafficking. Further west, in India's Bhadra Tiger Reserve, researcher Ullas Karanth, who has studied Indian tigers for more than fourteen years, tracks a population facing the same pressures. The film moves between these three fronts to show what protecting a single species actually requires on the ground.
